Installation instructions:
You can use either fastboot flasher or adb sideload to install this ROM.
If you are using adb sideload, we recommend LOS/PE recovery over TWRP, since TWRP doesn't work fully on A12 yet.
If using LOS/PE recovery, follow this:
1. fastboot flash recovery recovery.img
2. Reboot to recovery
3. Format data/factory reset
4. adb sideload ROM.zip
5. Reboot to bootloader
6. Repeat step 1
7. Reboot to system
You can either sideload magisk zip or can patch boot img. Recommended to root only after the first boot.
